Description: The neutral axis is clearly visible, up the centre of the image, with a region of ragged fibres indicating tensile failure to the left, and a smother, apparently crushed surface to the right where the beam was in compression. The holes and proud fibres in the tensile region are indicative of fibre pull-out which is a toughening mechanism in fibre composites.
